Benefits of technology

The present invention allows for easy removal, replacement, servicing, and interchange of components in a device. Some components are used only once and are then discarded, while others can be sterilized and reused. In some cases, components have intelligence that enables them to recognize the device to which they are attached and adjust their function or performance based on different factors.

Problems solved by technology

The prior art devices present a great disadvantage because the cord 208 has a length, size, and weight that restricts the mobility of the operator.
The cord 208 creates a tether for the operator and presents an obstacle for the operator and those around him / her during any surgical procedure using the handpiece 112.
In addition, the cord must be shielded and durable and is very expensive.
Another disadvantage exists in the prior art due to the frequency sensitivity of the matching circuit 108, the transducer 110, and the waveguide 114.
This architecture introduces transmission losses and electrical parasitics, which are common products of ultrasonic-frequency transmissions.
For this reason, maintaining constant current is not an effective way of maintaining a constant movement of the waveguide 114.
This precision brings with it a significant increase in cost.

Abstract

A battery-powered, modular surgical device includes an electrically powered surgical instrument operable to surgically interface with human tissue and a handle assembly connected to the surgical instrument. The handle assembly has a removable hand grip and a handle body. The hand grip is shaped to permit handling of the surgical device by one hand of an operator, has an upper portion and a cordless internal battery assembly that powers the surgical instrument. The internal battery assembly has at least one energy storage cell. The handle body is operable to removably connect at least the upper portion of the hand grip thereto and create an aseptic seal around at least a portion of the hand grip when connected thereto and electrically couple the internal battery assembly of the hand grip to the surgical instrument and thereby power the surgical instrument for interfacing surgically with the human tissue.
